Boundary Monitoring Services
Protect Your Site, Community & Compliance
Accurate, Defensible Boundary Monitoring for Construction Projects
Construction and demolition activities can have significant impacts beyond the site boundary - including dust emissions, noise disturbance and ground vibration. In London and across the UK, contractors are increasingly expected to demonstrate active control of these impacts, supported by robust monitoring data.
GreenAir Monitoring provides independent Boundary Monitoring services that help contractors, developers and asset owners meet planning conditions, manage environmental risk, and protect surrounding communities with confidence. Our monitoring solutions deliver clear, real-time evidence that environmental impacts are being properly managed - not assumed.

Boundary Monitoring & Regulatory Compliance (Key Requirements)
For construction projects in London, boundary monitoring is rarely optional. It is most commonly required through planning conditions, local authority controls, and statutory noise legislation. The key regulatory drivers are outlined below.
Control of Pollution Act 1974 - Sections 60 & 61
Local authorities have powers under the Control of Pollution Act 1974 to control construction noise, dust and vibration.
Section 61 Consents are frequently required for major or high-risk works and typically reference noise, dust and vibration monitoring as part of Best Practicable Means (BPM).
Where consent is not agreed, Section 60 Notices may be served, imposing enforceable limits and controls.
Boundary monitoring data provides objective evidence that agreed controls are effective and that site activities remain compliant.
London Plan & GLA Control of Dust and Emissions SPG
The Greater London Authority (GLA) requires construction projects to assess and control emissions under the Control of Dust and Emissions During Construction and Demolition Supplementary Planning Guidance.
This guidance requires:
Construction Dust Risk Assessments
Identification of sensitive receptors
Proportionate dust monitoring for medium- and high-risk sites
Ongoing review of mitigation effectiveness
Boundary dust monitoring is a recognised method for demonstrating compliance with these requirements.
We hold our work to high standards. We focus on sustainable results built on smart strategy and insight.
Local Authority Planning Conditions & Codes of Practice
London boroughs routinely attach environmental conditions to planning approvals, often requiring:
Boundary monitoring for dust, noise and vibration
Defined trigger levels and alert thresholds
Reporting to Environmental Health or Pollution Control teams
In areas such as the City of London, Codes of Practice explicitly require monitoring to demonstrate Best Practicable Means and proactive environmental management.
British Standards & Industry Guidance
Boundary monitoring is typically carried out in line with recognised UK best practice, including:
BS 5228-1 & BS 5228-2 – Noise and vibration control on construction sites
IAQM Guidance – Monitoring of dust in the vicinity of demolition and construction
These standards are frequently referenced in planning conditions and enforcement discussions.
Why Boundary Monitoring Matters
Boundary monitoring provides early warning and evidence-based control of environmental impacts that can otherwise lead to complaints, delays or enforcement action.
Construction activities may cause:
Airborne dust and particulate emissions affecting local air quality
Noise disturbance to nearby residents and businesses
Ground-borne vibration with potential nuisance or structural implications
Boundary monitoring allows these impacts to be measured, managed and mitigated in real time, rather than addressed reactively.
What We Monitor
Our Boundary Monitoring services are tailored to the risk profile and planning requirements of each site and may include:
Dust & Particulates
Continuous or near-continuous monitoring of particulate levels to identify elevated emissions and support timely mitigation.
Noise
Real-time boundary noise monitoring to demonstrate compliance with agreed limits and working practices.
Vibration
Sensitive vibration monitoring to protect neighbouring structures and manage nuisance risk.
Air Quality Indicators
Where required, additional air quality parameters can be monitored to support planning or stakeholder commitments.
How Boundary Monitoring Works
1. Site Review & Monitoring Strategy
We review planning conditions, site layout and surrounding receptors to define an appropriate monitoring approach.
2. Strategic Monitor Placement
Boundary monitoring equipment is installed at agreed perimeter locations to capture representative environmental data.
3. Continuous Data Collection
Data is logged and transmitted securely, providing a reliable record of site conditions throughout the works.
4. Clear, Defensible Reporting
Results are presented in clear formats suitable for planning authorities, Environmental Health Officers and internal review.
5. Ongoing Technical Support
Our team provides interpretation, advice on mitigation and support if monitoring data indicates elevated risk.
